(~11~C)Carbon monoxide (also referred to as [11C]CO, carbon-11 monoxide, or Carbon monoxide-11C) is a radiolabeled compound used in carbonylation reactions, synthesized efficiently from [11C]CO2 via fluoride-activated disilane-mediated conversion. This method achieves high conversion yields (up to 74%) under mild conditions, enabling rapid production of radiochemically pure compounds like [carbonyl-11C]N-benzylbenzamide with high radiochemical yield and purity. The process leverages commercially available reagents and standard laboratory setups, making it practical for PET tracer synthesis.

10456-04-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10456-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,5 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 10456-04:
(7*1)+(6*0)+(5*4)+(4*5)+(3*6)+(2*0)+(1*4)=69
69 % 10 = 9
So 10456-04-9 is a valid CAS Registry Number.

CO2 to [11C]CO conversion mediated by [11C]silanes: A novel route for [11C]carbonylation reactions

Taddei, Carlotta,Bongarzone, Salvatore,Haji Dheere, Abdul Karim,Gee, Antony D.

, p. 11795 - 11797 (2015)

A novel chemical methodology is described for the conversion of [11C]CO2 to [11C]CO. Diphenylmethyl silanes trap [11C]CO2 and release [11C]CO rapidly when triggered by TBAF. Released [

Instantaneous Conversion of [11C]CO2 to [11C]CO via Fluoride-Activated Disilane Species

Taddei, Carlotta,Bongarzone, Salvatore,Gee, Antony D.

, p. 7682 - 7685 (2017)

The development of a fast and novel methodology to generate carbon-11 carbon monoxide ([11C]CO) from cyclotron-produced carbon-11 carbon dioxide ([11C]CO2) mediated by a fluoride-activated disilane species is described. This methodology allows up to 74 % conversion of [11C]CO2 to [11C]CO using commercially available reagents, readily available laboratory equipment and mild reaction conditions (room temperature). As proof of utility, radiochemically pure [carbonyl-11C]N-benzylbenzamide was successfully synthesized from produced [11C]CO in up to 74 % radiochemical yield (RCY) and >99 % radiochemical purity (RCP) in ≤10 min from end of [11C]CO2 delivery.
